I need new parts for my sliding glass door

Your roller looks like it could be a match for either our 81-129 or 81-262. Look these two parts over to determine the better match. For the track cover, see our 80-102.

I don't know what kind of weatherstripping you need, unfortunately. We need a clear picture of its end profile in order to ID a match. Please also make sure that the sample you show us is whole and undamaged. The video below will go into more detail.
